2 Claims.

My invention relates to a hand held device provided With means forreceiving and clamping a variety of instruments such as massaging toolsor an ordinary safety razor, and provided with electrical operatingmeans imparting an oscillatory movement to the head of the tool such asa safety razor clamped in the device.

A wide variety of facial and other massage tools are in use whichrequire the tool to be rapidly moved over the surface of the skin, asfor instance rubber pads with projecting fingers which are used tostimulate blood circulation in the scalp, or small pads used to workfacial cream into the skin of the face and to tone up the skin,or'safety razors. The manipulation of such applicators involvesconsiderable effort if properly carried out and it is the general objectof my invention to provide a device to which a variety of tools of thekind referred to may be attached and which merely requires to be pressedagainst and guided over the skin, the tool being activated by theelectrical mechanism arranged in the device.

An object of my invention is to provide an applicator device adaptableto a wide variety of purposes by the use of tools usually used manuallyas well as those designed for machine operation, yet of simple andsturdyconstruction. Another object of my invention is to provide an applicatordevice providing a greater amplitude of the applicator tool than haspreviously been attained. V

A preferred embodiment of my invention is shown in the accompanyingdrawings but it is to be understood that various changes in andmodification of parts may be made by those skilled in the art withoutdeparting from the scope of the invention as intended to be defined bythe appended claims.

In the drawings:

Fig. 1 is a perspective view of the device of my invention showing awidely used form of safety razor mounted therein;

Fig. 2 is a vertical longitudinal section through the device shown inFig. 1;

Fig. 3 is a cross section taken on the line 33 of Fig. 2;

Fig. 4 is a side elevation with a part in section showing a facialmassage tool mounted in the handle;

Fig. 5 is a schematic wiring diagram showing the arrangement ofelectrical elements adapting the device to either A. C. or D. C.current; and

Fig. 6 is a perspective view of a clutch Jaw member.

In the drawings, the numeral I0 indicates the main section of the bodyof the device which may be molded from plastic material, and ispreferably formed by two sections I 2a and l2b secured together byscrews M to form a case considerably wider in one direction than theother and of a length such that it may be comfortably held in the hand.

Preferably but not necessarily one end of the body is closed by a plugl6 of resilient and insulating material secured in place by a flange l8fitting in an annular groove 20 formed in the two halves of the body.The opposite end of the body is provided with a relatively large bore24.

A tubular tool mounting 28 is arranged in the forward end of the handleand is supported therein by a heavy ring 30 of resilient materialfitting tightly on the tubular mount 28. A pair of pins 32 are set inthe tubular mount 28 and extend into bores 34 drilled at diametricallyopposite points into the wall of the bore perpendicular to the plane ofoscillation of the tubular member. The pins 32 serve to hold the tubularmember in position in the body I0 and also act as trunnion bearingstherefor.

The forward end of tubular mount 28 is threaded and a knurled round nut36 is screwed onto the threaded portion and acts to tighten jaws 38arranged within the tubular mount and retained therein in any suitablemanner. In the form of the invention illustrated the jaws are formed byslotting one end of a tube 40 fitting easily in tubular member 28, andproviding tapered shoulders at the forward ends of the jaws by bendingup the edges. Th end of the tube is closed by an end plug 42 fitting inthe inner end of the tubular mount. The tapered forward ends of the jawsare engaged by a tapered inner surface on nut 36 in the usual manner.

The tubular mount is oscillated about its trunnion bearing pins 32 by anelectromagnetic operating element 44 of any suitable kind. As shown inthe drawings the operating element comprises pole pieces 46 and winding48 with an armature 50 free to vibrate on a fiat spring mount 52 actingto normally hold the armature spaced from the poles. A bracket 50a isriveted at one end to armature 50 and at the other end to plug 42.Electric leads 54a, 54b are led through plug l6, which forms awatertight seal around them and one lead 55a is connected to a. terminal55 of the winding 48. In order to adapt the device to use with either A.C. or D. C. current, I provide a make and break or vibrator contact 58operated by movement of the armature 50. The contact comprises a fixedelement Gilmounted on the body I and a movable element 62 mounted on thearmature 50 but insulated therefrom by a block of material 65. A lead 66connects fixed contact element 60 to the other end of windin 48. Lead54b is connected to the movable contact element 62. It will be evidentthat as armature is attracted toward the pole pieces of theelectromagnet the circuit of the electromagnet is broken and thearmature will spring away from the pole pieces thus again completing theelectric circuit through winding 48 again attracting the armature andagain breaking the circuit. The vibrating movement of the armature 50 is.transmitted to the tool mount 28 by the bracket 5011. In order toprevent radio interference caused by sparking at the contact points 58a,a small capacitor'fita is connected across the contact points inparallel with leads 54a, 54b by leads:-;-68. Preferably a switchVii-,isprovided: on, the body I 0 by whichthedevicemay be switchedzonand oif. A suitable formis shown in; Fig. 2 consisting ofaxsmallpermanent magnet: mounted to slide on the outer surface oftheibody and-cooperating with apiece of softiron "lflmfastened to" theupper. arm of the contact. When .the magnet H! is slid into positionover ltd-the latter will be attracted andthe contacts IEBaheld: open butwhen magnet is :slid out of this. position the contacts are free-tofunction normally. No opening'in the body is required by the describedswitch construction.

Operation When it is desired to use-the device a tool having. a stem orhandle 12 such as a razor or applicator for facialcream is inserted inthetool mount 28-and clamped therein byascrewing up nut 36 to'tightenthe jaws against'the handle 12. The device may thenbe brought into"operation by switching on theelectric current-whereupon the head' ofthetool will be oscillated with great rapidity about the axis of the.pins32. ,If asafety razor of the usual elongated head'type-is to beused'the razor is clamped with its head extending in line with the wideface of the device resulting in a rapid oscillation of thecutting'edgein the direction of its length whichvwhen the razor is movedacross the :skin in a line perpendicular to the cutting edge results inthe-oblique cutting tion adapted to be held in the hand, and having an'opening extending through one end thereof;

an elongated tool holder adapted to securely hold a variety-of tools andextending through said opening; trunnion bearing pins extending fromsaid elongated tool holder into bores in the wall of the'opening; andelectrical means mounted in said hollow body portion and effective tooscillate the-inward end. of the-tool holder.

2. .An oscillator comprising: a hollow body portion adapted to be heldin the hand, andhaving an opening extendin through one end thereofanelongated tool I holderextending through said opening; a chuck mountedon said tool holder whereby a variety of tools may be interchangeablyfitted to. the outer end thereof; a pair ofprojections extending fromopposite sides of saidtool holder-and fitting in bores formed :in the:wall of the opening to form trunnion-bearingsfor the tool holder; a ringof resilient material under compressionbetweenthe outer surface ofythetoolholder and the wall ofv the opening and effective to seal saidopening while permit- 1 ting'oscillatory motion of the tool holder aboutits bearings; and electrical means mounted within'the hollow body andeffective to oscillate-the inward end of'sa-id tool holder.
